The Mauerova Family:
Klara Mauerova, and her sister, Katerina, were members of a cannibal cult called the Grail Movement. The mother tortured her eight and 10-year-old sons, Ondrej and Jakub, while relatives skinned them alive and made them eat there own flesh.
These acts occurred in the Czech Republic, and the two were arrested in October of 2009.
The young boys, aside from being forced to eat their own skin, were burned with lit cigarettes, forced to stand in their own urine for days and kept in cages or handcuffed to tables.
The goal of this cult was to create a person with a completely broken will.
The group was busted when a neighbor inadvertently picked up the signal from a baby monitor at the Mauerova home.
